We replaced ours with a standard household one. It's digital and programable (so we can set it to get warmer before we wake up or return from a hike, etc.).

We also wired in a fan above the dinette. The furnace blows onto the dinette, and although heat rises, it seems to make it to the thermostat before it gets into the bunk (shutting the furnace off while it's still chilly in the bunk). We have the option of leaving it on Auto-Heat (where the fan above the dinette comes on with the furnace), Fan On (leaving the fan on regardless of what the heater does, or leaving it off and can turn the fan on/off as we choose. We can also use the switch on the fan to turn it off while the furnace is on (if we don't want it blowing the heat up into the bunk).

Wow am I glad I joined this site today. We just picked up our new Arcticfox 1150 and one of the things I want to upgrade is the thermostat to a digital version. I'll be looking into this upgrade and apprecaite any more input.

Yep, my 2013 AF1150 is the same way. Its not my favorite way to cool the camper as the fan runs continually. But it does a good job so I cant complain too much.

As stated earlier I replaced the OEM thermostat with the LuxPro 2 wire digital for my furnace. It fits in the space where the OEM unit was and I was even able to use the mounting screws and holes from the old unit.

What I will type relates to recently built COLEMAN air conditioners here, from about 2004 and forward.

On the Coleman Mach AC's with a ceiling control switch/thermostat, it's usually possible to add a wall mount thermostat.

With a ceiling control, the mode switch is on one side and the twist thermostat is on the other side of the plastic ceiling air diverter. But, on the wall mounted version, these twist controls are just not there. IN THEIR PLACE, and also inside the air conditioner's air passages is a newly added control box/circuit board that will control with a wall thermostat you'll add, what was once the twist knob operation.

The new electronics box / circuit board will mount on screws or holes that are already in place in the roof unit.

A problem you may encounter is that not all campers have been prewired with multi-strand thermostat wire behind the walls when the camper was built. If you are lucky enough that the manufacturer put it there, this swap out becomes much easier. Since it would be very difficult to fish thermostat wire through solidly filled foam walls, the thermostat multi-wire can be run on the surface of the ceiling and paneling and put behind a decorative channel on the wall of the camper.

Luckily, ALL the work involved with changing this out can be done from within the camper by just one person. There's no need to remove the roof portion or even access the roof. The only thing one needs to get into the air passage is a phillips head screwdriver. And then, one only needs to reach up into the ceiling vent to remove and rewire the controls. This can be done standing on a small stool or kitchen ladder.

In fact, here is a video on Youtube of a fellow doing a similar changeout. Not HARD, but just a little tedious. Click here and watch this. To make this job simple, don't try to save any money by buying a cheaper thermostat at Lowes and trying to make it work on this setup. Buy the Coleman matching thermostat.
